Hi I remember having done this once recently on a test system. And I
strongly suggest you don't attempt unless you have a good backup. You
use the standard tools to resize the partition and then pvresize to see
the new size of the PV. Once you can see that the new size of the PV is
recognised by the VG you can allocate the space.
